To Fig. 5, absorbent structure has forefoot area (first area) 51, the rear region (second area) 52 and middle section 53 that is positioned at front waist area 11 vicinity referring to Fig. 3.Middle section 53 extends between forefoot area 51 and rear region 52, and is limited between the inflection section of opposite side edge 17c, 17d.In absorbent structure 17; Forefoot area 51 is thicker than rear region 52; More particularly, absorbent structure 17 comprise from forefoot area 51 extend to thicker section 55 of middle section 53, from thicker section 55 extend back the thickness tilting section 56 that tilts gradually with bottom side towards absorbent structure 17 and from thickness tilting section 56 extend to rearward end 17b than light filling bar 57.Though in this embodiment absorbent structure 17 by continuously in a longitudinal direction the monolayer that extends of Y form; But; Can use two-layer formation for thicker section 55,, perhaps can form and contain whole absorbent structure 17 than light filling bar 57 with plural layer so that this section 55 is thicker than remaining section.
But, should be noted that with regard to shape to keep; By the integrally formed absorbent structure 17 of monolayer; According to this illustrated embodiment, have more superiority than the structure that forms with the upper strata by two, because the thermoplastic fibre that cotton-shaped wood pulp cellulose and selectivity add mixes well.
Though hygroscopicity single layer structure 17 can be shaped with known method or equipment,, absorbent structure 17 can also alternatively form with the method that describes below.
< making the method for thick section 55, thickness tilting section 56 and light filling bar 57 >
A kind of equipment (not shown) comprises pipeline and rotary drum; Pipeline is used for supply such as hygroscopic materials such as cotton-shaped wood pulp cellulose and/or superabsorbent polymer beads; Rotary drum is formed with a plurality of depressions that are used to gather; Be suitable for below pipeline, transmitting along machine direction, the mould that be used for gather of hygroscopic material from pipeline supply to depression makes hygroscopic material can accumulate in the corresponding mould to form polymer (or block) (being the Liquid Absorption core).Drum is mesh-structured, and like this, the bottom of each mould is formed with a plurality of openings, and hygroscopic material can be sucked in the mould and accumulates in wherein through these openings.The depth dimensions of the mould that each is used to gather (length dimension from the upper surface of each mould to the bottom of each mould that is used to gather) depends on that each mould is used for forming thick section 55, thickness tilting section 56 or light filling bar 57.More particularly; Thick section 55 of absorbent structure 17 is formed in the mould that all has less depth dimensions; Light filling bar 57 is formed in the mould that all has big depth dimensions, and thickness tilting section 56 is formed on and is arranged between thick section 55 and the light filling bar 57 and all has in one group of mould of the inclination degree of depth.In the zone that comprises the mould that all has big depth dimensions, aperture openings preferably is adjusted at interval greater than in the zone that comprises the mould that all has little depth dimensions, can gather wherein with hygroscopic material desired number correspondingly forr a short time guaranteeing.In the zone that comprises the mould that all has the tilting bottom that is used to form thickness tilting section 56, preferably change the aperture openings interval of corresponding mould continuously.
As stated, absorbent structure 17 has the special shape that is limited uneven gauge on the whole, and wherein, body fluid (mainly be wearer discharge urine) can have on front waist area 11 in thick section 55 of requirement absorbability and absorbed reliably.Excretory body fluid volume forms less than the back waist region of front waist area 11 12 usefulness light filling bars 57 usually, so basic all sections of absorbent structure 17 are used for absorb body fluids as a whole.So absorbent structure according to the present invention has higher absorption efficiency than being shaped and being arranged as the traditional absorbent structure with even absorbability.In addition, the amount that is used for the hygroscopic material of Liquid Absorption core can be reduced to necessary minimum, correspondingly keeps manufacturing cost low thus.
Forming thickness tilting section 56 and light filling bar 57 makes the thickness of absorbent structure 17 12 reduce gradually from crotch area 13 towards back waist region; Therefore back waist region 12 is along wearer's body shape smooth deformation; Make back waist region 12 can mate wearer's body, improved the sensation of wearer diaper.Therefore and diaper 10 its thickness has as a whole reduced, and single diaper 10 can doubling, so front waist area 11 can be set level with back waist region 12 and be in the same place, and can not become huge, is able to one group of diaper 10 is deposited nattily.
In the traditional absorbent structure 17 that comprises direct neighbor and thick section 55 of ining succession each other and light filling bar 57, the flip-flop of thickness direction has caused remarkable rigidity difference and the step border between thick section 55 and light filling bar 57.As a result, uncomfortable sensation possibly caused to wearer in this step border, in addition, absorbent structure 17 maybe part crooked and/or distortion and cause leakage of body fluid.By contrast, according to this embodiment, thickness tilting section 56 be formed on thick section 55 and light filling bar 57 between, gauge changes lenitively thus, has avoided because remarkable rigidity difference and the step border that the gauge sudden change causes.In this way, this structure can not produce for wearer uncomfortable sensation, can be not crooked and/or distortion and cause that body fluid leaks at the boundary vicinity of correspondent section 55,56,57.
Will be described below each section 55,56,57 that how to form absorbent structure 17 now.Thick section 55 gauge is about 2.7 in the scope of about 3.3mm, the Liquid Absorption core in this section 55 can by quantitatively about 220 to about 260g/m
2Cotton-shaped wood pulp cellulose in the scope with quantitatively arrive about 180g/m about 140
2The mixture of SAP (superabsorbent polymer beads) in the scope forms.The gauge of light filling bar 56 is about 2.2 in the scope of about 2.8mm, the Liquid Absorption core in this section 56 can by quantitatively about 180 to about 220g/m
2Cotton-shaped wood pulp cellulose in the scope with quantitatively arrive about 180g/m about 140
2The mixture of SAP in the scope forms.In this mode, quantitatively being lower than in thick section 55 in the light filling bar 57.Specifically, the Liquid Absorption core in the light filling bar 57 quantitatively preferably thick section 55 quantitative about 50 in about 85% scope, to realize above-mentioned effect of the present invention.
The gauge of each section can use the PEACOCK Thickness measuring instrument to measure (gaging pressure: 12.5g/cm in the absorbent structure 17
2).More particularly; Can absorbent structure 17 be taken out from diaper 10; Thick section 55 zone with light filling bar 57 that correspond respectively to of connecting structure 17 is cut into the last about 50mm of being of longitudinal direction Y; Horizontal direction X goes up and is the size of about 50mm, to obtain test block, measures the thickness of the interlude of each test block then through this Thickness measuring instrument.
As from can seeing Fig. 4; In the rear region 52 of absorbent structure 17, light filling bar 57 is formed with first depressed area 61, wherein; A plurality of depression general alignment become " it " fonts when the longitudinal direction Y of absorbent structure 17 looks; And thickness tilting section 56 be formed with second depressed area 63 with light filling bar 57 adjacent areas 62, wherein, a plurality of depression general alignment become " it " fonts when the longitudinal direction Y of absorbent structure 17 looks.Under the effect of first depressed area 61 and second depressed area 63,, the rigidity with light filling bar 57 adjacent areas 62 of light filling bar 57 and thickness tilting section 56 do not form the corresponding rigidity that caves in and have in this way if being higher than them respectively.
As previously mentioned, according to this embodiment, the thickness of absorbent structure 17 can be regulated inclination limiting the different each other section of wettability power, and if do not take any appropriate action, so, this layout possibly cause the rigidity between every pair of adjacent segment poor.Poor in order to reduce this rigidity; Between thick section 55 and light filling bar 57, form the thickness tilting section; In addition; Forming first depressed area 61 and second depressed area 63 strengthening the rigidity of the adjacent adjacent area 62 of light filling bar 57 and thickness tilting section 56 and light filling bar 57, so, can further prevent reliably because the distortion and/or the shape of the absorbent structure 17 that the part cracking of absorbent structure 17 causes are caved in.Otherwise, in the absorbent structure that comprises light filling bar 57 17, in the process of using this absorbent structure, the shape of this light filling bar can be caved in easily, causes leakage of body fluid.But this light filling bar 57 can form depression in advance, to avoid this disadvantageous situation.
The a plurality of depressions 60 that limit first depressed area 61 and second depressed area 63 have the round-shaped of cardinal principle uniform-dimension, in first depressed area 61, closely are arranged in together, and in second depressed area 63, are not closely aligned together so.So the depression 60 total occupied area percentage ratios in whole first depressed area 61 are higher than the depression 62 total occupied area percentage ratios in whole second depressed area 63.Specifically, depression 60 arrives in about 18% the scope about 12% at total occupied area percentage ratio of first depressed area 61, and the 60 total occupied area percentage ratios in second depressed area 63 that cave in arrive in about 9.0% the scope about 5.0%.Each cave in 60 the length dimension on the thickness direction Z (being the degree of depth) about 0.2 in the scope of about 0.5mm.Be understood that; The concrete numerical value of total occupied area percentage ratio can appropriate change; The pattern that forms depression is not limited to " it " font, but can from various patterns, suitably select, and 60 the shape of caving in also is not limited to circular shape; But can be from such as suitably selecting the different shapes such as oval, rhombus and reed shape, as long as can guarantee above-mentioned mutual relation.
As stated; In first depressed area 61; Depression 60 is than arranging tightr in second depressed area 63; Higher total occupied area percentage ratio is correspondingly arranged,, make the rigidity value of the adjacent area that is adjacent 62 of light filling bar 57 and thickness tilting section 56 to be adjusted to basically and be equal to each other with the stiffness variation that takes place in the adjacent area 62 adjacent of distinguishing the stiffness variation that takes place in the light filling bar 57 and thickness tilting section 56 with light filling bar 57.In this way, first depressed area 61 and second depressed area 63 that in the adjacent area that is adjacent 62 of light filling bar 57 and thickness tilting section 56, form respectively make that the rigidity value of absorbent structure 17 integral body is even basically.Be through under the situation on the wearer's body at diaper 10, absorbent structure 17 is not therefore than there being this structure can resist fold and distortion or distortion more, even crotch area 13 is owing to fold takes place the wearer leg exercise.
Though the rigidity according between each rigidity value of thickness tilting section 56 and light filling bar 57 and/or these two sections and thick section 55 is poor; Can suitably design the zone that will form first depressed area 61 and second depressed area 63 respectively; But; Near any boundary line 65 that preferably is formed between crotch area 13 and the back waist region 12 among first depressed area 61 and second depressed area 63, along vertically striding across this boundary line 65.Reason is such: the part that absorbent structure 17 is arranged in crotch area 13 always keeps in touch the thigh and the inguinal region of wearer, easily because the motion of wearer's body receives the influence of external force.In other words, can rule of thumb predict: absorbent structure 17 is most probable distortion or distortion near the boundary line 65 between above-mentioned part and the back waist region 12.Therefore, be enough to prevent that in order to guarantee rigidity thickness tilting section 56 and/or light filling bar 57 are out of shape or twist near boundary line 65, preferably in the above-mentioned qualifying part of absorbent structure 17, form depression.
Referring to Fig. 6, illustrate and to be used for carrying out equipment and the method for depression processing so that absorbent structure of the present invention to be provided.Continuous absorbent structure 71 corresponding to a plurality of absorbent structures 17 is carried along machine direction MD by the conveying roller (not shown).Through forming this continuous absorbent structure 71 with Liquid Absorption core wrap sheet parcel monolayer or multilayer liquid absorbent cores, wherein each several part 71a is corresponding to light filling bar 57, and each several part 71b is corresponding to thick section 55.
The step that forms depression comprises that clockwise rotating being recessed to form roller 72 and rotating counterclockwise above continuous absorbent structure 71 is arranged to face the anvil roller 73 that is recessed to form roller 72 and has smooth outer peripheral face.The outer circumferential surface section branch that is recessed to form roller 72 is formed with ridge 74 that increases gradually along circumferential thickness and a plurality of pins 75 that are recessed to form that stretch out from the surface of this ridge 74.Being recessed to form pin 75 is divided into first group and is recessed to form pin 77 and second group and is recessed to form pin 80; First group is recessed to form pin 77 and is formed in the thick sub-position 76 corresponding to the ridge 74 of first depressed area 61 of single absorbent structure 17; Second group is recessed to form pin 80 and is formed in the Bao Zi position 78 corresponding to the ridge 74 of second depressed area 63 of single absorbent structure 17; Wherein, second group is recessed to form pin 80 to the first groups and is recessed to form pin 77 and arranges more loosely.In order to guarantee that continuous absorbent structure 71 stably forms depression 60, can under the temperature of suitably control, heating be recessed to form pin 75, make that the flat member that constitutes continuous absorbent structure 71 can not sealed around being recessed to form pin 75.
